HAIR-WAVING CURLER ROD.

Application filed November 13, 1926. Serial No. 148,177.

My invention relates to curler rods, and relates particularly to haircurler rods employed in the art commonly known as permanent waving.

In a prior application for patent, Serial No. 109,077, filed May 14,1926, I disclosed a form of curler rod comprising a rod element and atubular element telescoped over the rod, the two elements beingremovably i seecured together and being relatively rotatable but beingfrictionally restrained from easy rotation by the elements beingspring-pressed together in contacting portions thereof. Curler rods ofthis general type are now in use and since, during a waving process aconsiderable number of such rods are in use at one time, strands of hairof a. patient operated upon being wound upon each of such curler rods,it is highly important that the curler rods be made of very lightmaterial and the rod element of such curlerrods is therefore commonlymade of aluminum or aluminum alloy material, the

tubular element therefor being made quite thin and of brass, Germansilver, or the like.

I have found that the hair-treating materials employed in the form of asolution during the hair waving process, have a deleterious effect uponthe contacting surfaces of the aluminum rod and enclosing metallic tube,and since it is impracticable to employ other than dissimilar metals forthe rod and tube, this deleterious effect which is accomplished by anelectrolytic action between the rod and tube acting as electrodes, andthe hair-treating materials in solution acting as an electrolyte, iscommonly had to a degree whereby relative rotation of the tube androd'may be prevented.

This action also sometimes progresses to such an extent that corrosionof one of the engaging surfaces, and the formation of a base material incontact with such surface, prevents removal of the tube from the rod'which might otherwise permit cleaning 0 the corroded surfaces andremoval of the base material.

My present invention, therefore, has for its object to prevent suchundesirable amount of electrolytic action as will cause the contactingsurfaces of the rod and tube to so adhere together as to restrict theirrelative rotation and their relative endwise movement duringdisassociation of the tube and 515 rod.

Another object of my invention is to lubricate the contacting surfacesof the tube and rod, whereby with a given spring pressure exertedbetween the tube and rod, there will always be approximately 7 the sameamount of frictional resistance to rotation which may be practicallypredetermined.

Another object of my invention is to provide an improved curler rodcomprising concentric telescoped portions bet-ween which electrolyticactionwill be prevented or limited to a nonobjectionable amount, andwhich may be capable of being relatively rotated after successive'hairwaving opera tions.

Another object of my invention is to provide a hair curler having a pairof relatively rotatable concentric parts, having a lubricating means toensure relative rotation between the parts, the lubricating means beingeasily replaceable.

Other objects of my invention and the invention itself will becomeapparent from the following description of an embodiment of myinvention, and in which description reference will be had to theaccompanying drawings illustrating the said embodiment.

Referring to the drawings:

Fig. 1 shows a plan view of a curler rod embodying my invention,enlarged;

Fig. 2 is a. similar View of the rod portion thereof per se.

Fig. 3 is a similar view of the tube portion thereof per se. 7

'Fig. 4 is a transverse section taken on the line 44 of Fig. 1.

I Fig. 5 is a longitudinal section taken on the line 5-5 of Fig. 1.

Fig. 6 shows a perspective view of a wick element of lubricant absorbentmaterial employed in the embodiment illustrated in the foregoingfigures.

. Referring, now, to the different figures of drawing, in all of whichlike parts are designated by like reference characters, at 1 I show arod which is split at 2 to form two outwardly bowed portions 3 and 4,the splitportion of the rod extending for, perhaps, one quarter of thelength of the rod, the exterior surface of the rod being annularlygrooved at 5 and 6, adjacent the ends of the rod. The end having thegroove 5 is bifurcated by a slot 7 to form a tip to which a strand ofhair may readily be secured by tying duringthe preparation of the hairiii for the waving process. After the manner described in my (co-pendingaplication, Serial No. 87,777, tiled Feb. 20, L926, the other end of therod, per is flattened, as shown at 8. to permit the operator to turn therod by hand to tighten the hair, as will be well undersood by relerenceto my aforesaid co pending aplications.

At, t! 1 show a collar tightly titted upon the end oi the rod 1,adjacent its tlattened end and between such tiattened end of the groove(5, this collar forming a stop for the tube 10: when the tube 10 istelescoped over the rod 1. the tube 10 has an inwardly extending annularrib 11 adjacent one end and which end slotted at 12. the slot 12extending longitudinally medially of the tube from its end through itsopposite walls to permit yielding ol' the two separated wall portionswithin the elastic limit of the resilient metallic material of which thetube is made. The tube 10 has its other end intnrned slightly, as shownat 123. The inturned end ot the tube 10 makes tontact with the rodadjacent to its groove 5, but spaced therefrom slightly, and preventscontact between the inner walls of the tube and the rod '1. in otherportions adjacent the inturned end 13 of the tube.

\Vithin the slot. 2, I place a wicl: of felt, or like lubricantabsorbent material, shown at l t, the wick per se being illustrated inFig. (l, and comprises a strip of felt, or the like, of a widthpreferably about the diametero'l' the rod 1 and ot a length such that,after being impregnated with a lubricant such as Vaseline or the like,it may be placed within the slot 2 between the outwardly bowed portions3 and at ol the rod, and may make contactby its edge portions 15 withthe inner walls oi the tube. The lubricant containii'ig pad 14 beingfirst inserted into the slot 2 of the rod 1, the tube 10 is thentelescoped over the rod, as illustrated in Fig. 1, to home position,wherein the in \vardly extending rib 11 is projected within the annulargroove ti, the rib being held witlr inthe groove ti by the inherentresiliency oi the metallic material of the tube, the bifurcated arcuateportions 16 and 17 of the tube tending to retain their normal unstressedform.

The presence of the lubricant contained within the rod keeps thecontacting portions 01 the rod and tube coated with a lilm of lubricant,whereby electrolytic action between the tube and rod is etl'ectuallyretarded, it not entirely prevented; The. exterior surface of the rodmay be preliminai ily lubricated by rubbing with a cloth con taininglubricant before assembling the rod within the tube, or dependence maybe placed upon the lubricant contained by the pad 14. ll tind that thelubricant contained in the pad is sull'icient to prevent the deleteriousell'ect of electrolytic action in the presence of a borax sohition orother hair-treating material in solution, between the rod and tube, evenwhere the rod and tube are of metals having widely differentelectrolytic potential values.

Having thus described my intention in a specific QIIllJOClilDGIllL, I amaware that nu merous and extensive departures may be made from theembodiment herein illustrated and described but without departing fromthe spirit of my invention.
